A corner could be used to produce phantom images and then one cabinet could be enough to get stereo. I will think about how to arange speakers to do that.
In fact the baby MPLs are small enough to try that.

Original (1958-1972) Lowther Audio Vector can be regarded as an early example of a flooder

Lowther USA Bass Horn Speaker Cabinets.

pictures attached are of DIY homemade Audiovector

I've found that website too and there is written that:

"Audiovector was designed by British sloping ceilings, with the expectation that the sound of the horn, the striker up, will affect the listener. Just a Guido, the system is on the attic floor with the ceiling. But now it is perpendicular to the slope. According to Oleg, earlier, when the system was placed parallel to the slope of the ceiling, it sounded better.

And:

"The scene is passed very well, but a bit strange - a voice somewhere near the ceiling."

P.S. I was using translator from russian to english.

yeah, I have noticed that, perhaps such a waveguide is not the best idea in case of flooding?

best!

Try the folowing . Use "normal" speakers and put them more and more apart. If you put them more then 3m apart something strange happens. The voice comes from high up !
It is called the elevation effect and was researched by Blauert. Give your speakers +3dB of gain @ ca.7kHz and the same happens even when they are closer then 3m.
Graaf, you totally underestimate the problem.
